How to Fix a Washing Machine That Won’t Drain and Has a Burning Smell
A washing machine that refuses to drain and emits a burning smell is a homeowner’s nightmare. This combination of issues usually points to a significant problem, but with a systematic approach, you can often diagnose and resolve the issue yourself, saving time and money on repair services.
Understanding the Problem
Before diving into the fix, it’s crucial to understand why these two problems – no draining and a burning smell – are occurring simultaneously. The burning smell often indicates a motor or electrical component overheating, potentially due to being overworked or obstructed. The inability to drain is often related to a blockage in the drain pump, drain hose, or drainpipe. When the pump is blocked and tries to force the water through, it can overheat and cause the burning smell.
Step-by-Step Troubleshooting Guide
Follow these steps to safely and effectively troubleshoot the issue:
1. Safety First: Disconnect the Power
- Unplug the washing machine from the electrical outlet. This prevents electrical shock during the repair process.
2. Check the Drain Hose
The drain hose carries wastewater from the washing machine to the drainpipe. A kinked, clogged, or improperly installed drain hose is a common cause of draining issues.
- Inspect the hose: Look for any kinks, bends, or visible damage along the hose’s length.
- Detach the hose: Disconnect the hose from both the washing machine and the drainpipe. Have a bucket ready to catch any residual water.
- Check for clogs: Run water through the hose to check for blockages. You can also use a long, flexible brush or a plumbing snake to dislodge any debris.
- Reattach the hose: Ensure the hose is securely connected to both the washing machine and the drainpipe. Make sure it is not kinked or bent.
3. Examine the Drain Pump Filter
The drain pump filter is designed to catch lint, hair, and other small objects that could clog the pump. A clogged filter restricts water flow, preventing the machine from draining properly and potentially causing the motor to overheat.
- Locate the filter: The filter is usually located at the front of the washing machine, behind a small access panel. Refer to your owner’s manual if you can’t find it.
- Prepare for water: Place a shallow pan or towel beneath the access panel to catch any water that spills out when you remove the filter.
- Remove and clean the filter: Carefully unscrew or unclip the filter and pull it out. Remove any debris, such as lint, hair, buttons, or coins. Rinse the filter thoroughly with water.
- Reinstall the filter: Securely reattach the filter to the washing machine.
4. Inspect the Drain Pump
If the drain pump filter is clean, the pump itself might be faulty or obstructed. The burning smell can originate from the pump motor attempting to run while blocked.
- Access the pump: This usually involves removing the front or back panel of the washing machine. Refer to your owner’s manual for specific instructions.
- Visually inspect the pump: Look for any visible damage or obstructions.
- Check for obstructions: Manually rotate the pump impeller (the fan-like part inside the pump). If it’s difficult to turn or doesn’t turn at all, there may be an obstruction. Use pliers or tweezers to carefully remove any debris.
- Test the pump (Advanced): If you have a multimeter and are comfortable working with electricity, you can test the pump’s continuity to see if it’s electrically sound. A lack of continuity indicates a faulty pump requiring replacement.
- Consider Replacement: If the pump is faulty, consider replacing it. Replacement pumps are available at appliance parts stores or online.
5. Check the Air Dome/Pressure Chamber
Some washing machine models have an air dome or pressure chamber connected to the tub. This component can sometimes become clogged with soap residue and debris, affecting draining performance.
- Locate the air dome: It’s usually a small, round chamber connected to the side of the outer tub with a rubber hose.
- Disconnect and clean: Disconnect the hose from the air dome and the tub. Clean out any buildup inside the hose and the chamber with a small brush or wire.
- Reattach: Reconnect the hose to the air dome and the tub, ensuring a secure fit.
6. Inspect the Washing Machine Motor
The burning smell could indicate a problem with the washing machine’s main motor, especially if the machine strains during the wash or spin cycle.
- Visual Inspection: Remove the washing machine’s back panel and visually inspect the motor. Look for signs of burning, melted plastic, or frayed wires.
- Check the Belt: If your machine uses a belt-driven motor, inspect the belt for wear and tear. A worn or broken belt can cause the motor to overheat.
- Smell Test: Carefully smell the motor itself. A strong, acrid burning smell is a clear indication of motor failure.
- Motor Replacement (Advanced): Replacing a washing machine motor is a complex task best left to professionals. However, if you are experienced with appliance repair, you can find replacement motors online. Make sure to match the motor’s specifications to your washing machine model.
7. When to Call a Professional
If you’ve followed these steps and your washing machine still won’t drain and has a burning smell, it’s time to call a qualified appliance repair technician. The problem might involve more complex electrical or mechanical issues that require specialized knowledge and tools. Continuing to operate a malfunctioning washing machine can lead to further damage or even pose a safety hazard.
Prevention Tips
- Regularly clean the drain pump filter: This prevents clogs and ensures proper water flow.
- Use the correct amount of detergent: Excessive detergent can lead to soap buildup and clogs.
- Avoid overloading the washing machine: Overloading puts strain on the motor and other components.
- Inspect the drain hose regularly: Check for kinks, bends, and damage.
- Run a cleaning cycle: Use a washing machine cleaner periodically to remove soap residue and buildup.
By following these troubleshooting steps and preventative measures, you can address the issue of a washing machine that won’t drain and has a burning smell, saving you money and extending the life of your appliance.
